Quick answer: if the project may need to move between UV, solvent, and aqueous-entry testing, CHLUMIAG® 3170 is usually the more flexible first benchmark because Longchang supports it for UV and solvent systems and also allows aqueous use after hydrophilic-solvent pre-dilution. If the formulation is already committed to a water-based-only route, CHLUMIAG® 5000 is the cleaner first screen because Longchang positions it as a water-based-only emulsion. If the buyer is working in a solvent-based coating and specifically cares about marker-pen wiping resistance, blocking resistance, and low-temperature-bake anti-graffiti logic, AG-D9000 deserves earlier review.
This page is intentionally narrower than the already-live anti-graffiti additives for coatings overview and different from the newer 3000 vs 3170 vs 5000 comparison. That earlier comparison is mainly about 3000, 3170, and 5000 as system-boundary options inside the CHLUMIAG® branch. This page answers a different buyer question: when should the team choose 3170, 5000, or AG-D9000 once the shortlist has narrowed to water-based-entry flexibility versus water-based-only emulsion versus solvent-side marker-wipe performance?
Why this comparison deserves its own page
Easy-clean and anti-graffiti buyers often reach a more specific decision point after reading a broad function page. They already know the project needs easier cleaning, stain-release support, anti-sticking, or better maintenance behavior. The next question is not always which anti-graffiti additive family. It is often:
- Do we need one route that can still bridge into aqueous work?
- Do we want a cleaner water-based-only emulsion route?
- Or is the real job a solvent-side coating that will be judged by marker wiping, blocking resistance, and bake-process behavior?
That split is commercially useful because these three products do not enter the formulation the same way, even though all three sit near the easy-clean and anti-graffiti branch.

| Buying factor | CHLUMIAG® 3170 | CHLUMIAG® 5000 | AG-D9000 |
|---|---|---|---|
| Main supported system window | UV √, solvent √, aqueous with hydrophilic-solvent pre-dilution | Water-based only | Solvent-based |
| What pushes it forward first | One route that can stay in UV or solvent work but still enter aqueous testing | Cleaner water-based-only easy-clean emulsion route | Marker-wipe, blocking resistance, and solvent-side anti-graffiti programs |
| Recommended dosage | 0.05% to 1% | 0.5% to 5% | 0.5% to 3% |
| Important processing note | Aqueous use requires pre-dilution with hydrophilic solvent | 50% active emulsion and only for water-based systems | Dilute to 10% to 20% with xylene before addition |

When CHLUMIAG® 3170 is the better fit
CHLUMIAG® 3170 should move to the front when the buyer wants an easy-clean or anti-graffiti route that still keeps formulation flexibility open. Longchang supports it as a multi-component modified polysiloxane with a recommended dosage of 0.05% to 1%. The product page supports it for UV systems and solvent systems, and also says it can be used in aqueous systems after pre-dilution with a hydrophilic solvent.
That system window matters because some buyers are not ready to commit the first lab round to a water-based-only emulsion. They want one benchmark that can stay inside solvent or UV work while still reaching an aqueous route if needed. Longchang also places 3170 in protective coatings, general industrial coatings, leather coatings, and architectural coatings, which gives it a broader application frame than a single narrow use case.
From Longchang’s own company-controlled anti-graffiti branch already live on the site, 3170 is also positioned as a reactive easy-clean route that supports durable hydrophobic or oleophobic surface behavior, anti-sticking, and easier maintenance when the resin match is right.
- Best fit: buyers who want one comparison point that can stay relevant across UV, solvent, and controlled aqueous-entry testing
- Main strength: broader system flexibility with a lower starting dosage range
- Main watchpoint: aqueous use depends on hydrophilic-solvent pre-dilution, so it should not be treated like a water-based-only emulsion route
When CHLUMIAG® 5000 is the better fit
CHLUMIAG® 5000 is the cleaner first route when the buyer already knows the project should stay firmly water-based. Longchang supports it as a multi-component modified polysiloxane emulsion with 50% active ingredient and a recommended dosage of 0.5% to 5%. The product page explicitly marks it for water-based systems only, while excluding solvent-based and oil-based use.
That is the main commercial value. 5000 is not a flexible bridge product. It is the more direct route when the project wants an aqueous emulsion path without the extra handling logic required by 3170. Longchang’s already-published anti-graffiti branch on the site also positions 5000 around easy-clean, anti-graffiti, anti-sticking, hydrophobic, and oleophobic surface behavior inside water-based coating logic.
- Best fit: water-based industrial, protective, or related coating work that wants to stay fully inside an aqueous system window
- Main strength: clear water-based-only fit instead of cross-system compromise
- Main watchpoint: because it is a 50% active emulsion and only for water-based systems, buyers should not compare it as if it were the same physical route as 3170 or AG-D9000
When AG-D9000 is the better fit
AG-D9000 deserves earlier review when the project is not an aqueous-entry discussion at all. It is a solvent-based anti-graffiti route and the company-supported page is much more explicit about marker-pen wiping resistance, blocking resistance, and practical process conditions. Longchang describes it as polydimethylsiloxane with hydroxy group and supports it with improved surface anti-graffiti and cleanability, improved water contact angle, hydrophobicity, and oleophobicity.
That makes AG-D9000 commercially different from the more general CHLUMIAG® water-based-entry discussion. The same product page also gives two process notes that matter in real buying decisions:
- Longchang suggests diluting it to 10% to 20% with xylene before addition.
- For two-pack low-temperature baking systems, Longchang suggests using acrylic resin with high hydroxyl value and prolonging bake time to improve anti-graffiti performance.
Longchang also says compatibility should be checked before use in varnish, which is a practical formulation watchpoint rather than a marketing footnote.
- Best fit: solvent-based coatings where marker wiping, blocking resistance, and bake-process anti-graffiti performance matter early
- Main strength: more explicit solvent-side surface-maintenance and marker-cleanability guidance
- Main watchpoint: resin choice, bake time, and varnish compatibility deserve real screening discipline
How buyers should choose before requesting samples
1. Start with the real system boundary
If the project must stay water-based, 5000 usually deserves earlier review. If the team wants a route that can still move between UV, solvent, and aqueous-entry work, 3170 is more natural. If the route is already solvent-based and the customer is asking about marker wiping or blocking resistance, AG-D9000 should move up.
2. Separate water-based-entry flexibility from water-based-only commitment
3170 and 5000 can both enter water-based conversations, but not in the same way. 3170 is the bridge route with hydrophilic-solvent pre-dilution. 5000 is the direct emulsion route.
3. Do not hide process reality
AG-D9000 becomes more useful precisely because the product page gives practical process guidance, including xylene pre-dilution and the two-pack low-temperature baking note. That should be part of the first buying screen, not discovered too late.
4. Keep the final KPI visible
If the target is only appearance, another additive family may deserve earlier review. This page is for coatings judged by cleanability, anti-graffiti performance, anti-sticking, marker wiping, or maintenance behavior after cure.
5. Use a short first sample round
For many buyers, the cleanest first sample round is one route for aqueous-entry flexibility, one route for water-based-only emulsion, and one route for solvent-side marker-wipe performance. That usually gives faster insight than comparing all three as if they were interchangeable silicone additives.

FAQ
Which product is the cleanest first benchmark for water-based-only easy-clean coatings?
Usually CHLUMIAG® 5000, because Longchang explicitly positions it as a water-based-only emulsion route and excludes solvent-based and oil-based systems.
When should 3170 move ahead of 5000?
3170 should move ahead when the project still needs cross-system flexibility and may move between UV, solvent, and aqueous-entry testing. Its aqueous route depends on hydrophilic-solvent pre-dilution, so it is more of a bridge route than a water-based-only one.
Why is AG-D9000 not just another version of the CHLUMIAG® water-based-entry discussion?
Because Longchang positions AG-D9000 much more specifically around solvent-based work, marker-pen wiping resistance, blocking resistance, water contact angle improvement, and process notes such as xylene pre-dilution and low-temperature baking guidance.
What should buyers watch before using AG-D9000 in varnish?
Longchang says compatibility should be evaluated first before use in varnish, so buyers should treat varnish fit as an active screening item rather than assuming direct interchangeability.
Need a tighter easy-clean shortlist?
If your coating project is being judged by easy cleaning, anti-graffiti behavior, marker wiping, or blocking resistance, first decide whether the real job is aqueous-entry flexibility, water-based-only emulsion work, or solvent-side marker-wipe performance. That usually leads to a cleaner Longchang shortlist than treating 3170, 5000, and AG-D9000 as if they served the same formulation path.
